GUT-OFF AND DRAIN FOR ICIOUSVE-PLUMBINIG.

Specification of Letters Patent.

Application filed December 12, 1910. Serial No. 596,819. f

To all whom t may concern Be it known that I, CHARLES G. WOODS, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Cut-Offs and Drains for House-Plumbing, of which the following is a specification, containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. l

My invention relates "to improvements in cut-oifs and drains for house plumbing, the object of my invention being to construct al simple means which is yco-nnected with the service pipe whereby the water supply may be cut off and at the same time drain the service pipe to prevent freezing.

With the above purposes in view my invention consists in certain novel features of nected with the service pipe 1 by means of the valve housing 4. Within the housing 4 is a partition 5 dividing the housing into two compartments, one of which is in open communication with the supply pipe 3 and the other in open communicationwiththe service pipe 1. W'ithin the partition is ai port 6 normally affording communication between the compartments leading vrespec- :t-ively to the supplypipe 3 and service pipe 1. yConnected with the housing 4 and preferably formed integrally with the housing in alinement with the port 6 is a tubular extension 7 which acts as a drain ope-ning for the compartment ofthe housing in communication with the service pipe 1 and the service pipe 1 withall of its connections, and at the lower end of the tubular extension there is formed a valve seat 8. Connected with the tubular extension 7, by means` of the coupling 9, is a waste pipe 10 which leads off to a sewer or other drain.V

Awardly and upwardly.

11 designates a valve stem which extends through the entire housing, through the port 6 and beyond the lower end of the tubular extension 7, and carried by the stem is a valve 12 for controlling the port- 6 and a valve 13 for controlling the flow of water through the waste pipe 10.

- Located between the valve 12 and the sleeve nut 14, which nut forms a water-tight joint between the stem llan'd the interior of the housing 4, is an extensile .coil spring 15 which normally acts to seat the valve 12 and hold the valve 13 open.

rI`hel parts just described are preferably located in the cellar of the building, at any rate, they are usually placed at a point wherein the valve is net subjected to a freezing temperature.

For the operation of the valve, I have provided a means, which will be hereinafter described in detail, preferably located at a convenient andaccessible point in the building on one of the floors above the cellar, which ymeans comprises the actuating rod 16 which is connected with the valve stem 11 by means of the reducing coupling 17 and which rod is of a length to extend to one or more of the floors of the building. In the illustration I have shown only one of the valve operating devices, but have extended the actuating rod beyond said valve operating device and have assumed that the illust-ration would suffice to make it clear that I intend using, if desired, more than one of the valve operating devices on the actuating rod.

Fixed upon a suitable support is a bracket v18, which bracket carries a sleeve 19, and

secured to the sleeve is a cam sleeve 20, the upper` margin of which is inclined rear- Arranged for movement upon the sleeve 19 is a second cam sleeve 21, the lower margin of which is shaped to conform with the upper margin of the sleeve 20, which sleeve 21 is provided with an actuating lever 22. Arranged for contact with the upper end of the sleeve 21 and secured to the actuating rod 16 is a collar 23. f

As shown in the drawings, when the lever 22 occupies the position shown` in solid` lines the. cam sleeves have served to movek and hold the valve 12 in an open posit-ion and Patented J an. 7,1913.

the valve 13 in a closed position, this is the normal position of the valves, affording communication between the supply pipe 3 and service pipe 1 and cutting off communication between the service pipe 1 and drain pipe 10. If it be desired, at any time, to cut orf the water supply the lever 22 is thrown to a position shown in dotted lines in Fig. 1. In moving` the lever to the posi tion just described the cam sleeve 21 is lowered and, by reason of the action of the spring` 15, the valve 12 is seated and the valve 13 opened. In this position it is obvious that the port 6 will be closed, thereby cutting oit communication between the supply and service pipes and that the water in the service pipe will drain through the housing, the tubular extension 7 and drain pipe 10 to the sewer or other outlet. In order to facilitate the movement of the water, to drain, the service cock 2 may be opened thereby admitting` atmospheric pressure. I-Iowever, I have provided an automatic air inlet valve 24 which is connected with the service pipe and in which there is a weighted ball 25, which, by reason of its peculiar construction, prevents the discharge of water and admits air when the water pressure is reduced.

I claim:

In an apparatus 'of the class described, a valve, spring actuated in one direction, a rod detachably connected with the stem of the valve for the operation of the valve from a distance, a bracket iixedly located a distance from the valve, a sleeve iXed to the bracket, a cam iiXed to the sleeve, a movable cam carried by the sleeve and a collar secured to the rod to be engaged by the movable cam.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
